Title: Improvements in and relating to composite power units consisting of gas turbine and steam engine
IPC: F01K23/00
Filed: 1936-01-23
Abstract: 469,119. Turbine plant. HERPEN, A.-T., and VORKAUF, H. Jan. 23, 1936, No. 2161. Convention date, Jan. 23, 1935. [Class 110 (iii)] In a plant comprising a rotary gas generating chamber 6, a gas turbine 7, a rotary steam generator 8, and a steam turbine 12, the compressor 1 supplying combustion air is driven so that it may be regulated independently of the gas turbine. The compressor 1, Fig. 1, is driven by one of the two oppositely-run ning rotors of a steam turbine 12. The other of the two rotors rotates with the steam generator 8 and steam from the generator passes to the turbine by an axial bore 11. Air from the compressor passes through the hollow blades 2 of the gas turbine and is delivered to the chamber 3. Fuel is supplied by a pipe 20 into a trough 21 and splashes from ring to ring of a series 22 in the inlet to the combustion chamber. The last rings of blades of the steam turbine cooperate with fixed blades carried by a central partition and the output of the compressordriving rotor is raised by throttling the exhaust from that rotor by means of a ring valve 19 or.by differential operation of separate throttle valves controlling the outlets from the chambers 16, 18. The compressor may be driven by the high-pressure stage of an ordinary turbine ; the low-pressure stage being coupled to the gas turbine and rotary steam generator. The output to the compressor may be regulated by a back-pressure valve between the turbine stages. The compressor may also be regulated by means of a throttle valve 40 in the air delivery pipe.

[Also in Group XXXV] A low-pressure axial-flow or radial-flow blower for paint-spraying appliances is driven through transmission gearing by an induction motor, the blower, gearing and motor being housed in a common casing. An induction motor 4, Fig. 1, drives a two-stage blower through pulleys 8 and a V-belt 9. The larger pulley 8 may be split, as shown, the two parts of the pulley being spaced apart by interchangeable inserts 29 to provide adjustment of the belt tension. Guide blades 18 are carried by discs 19, 20 which are spaced apart by a ring 21 and held in place in a recess in the discharge orifice 12 by a cover 13 having a discharge opening 30. A similar cover 13 is provided at the suction end of the casing 1 and may incorporate an air filter. Openings 16 in a partition 15 may be so formed as to impart whirl to the air. A recess 22 is bridged by a handle 23 which may be removable or formed integral with the casing 1. The last set of guide blades may be replaced by a radial or tangential passage in the adjacent cover 13. To permit the use of several paint-spraying appliances, several discharge openings may be provided, those not in use being closed by screw caps. The blower may comprise a single axial-flow stage. In the modification shown in Fig. 2, the blower is driven through friction gearing comprising rubber-covered wheels 24, 25. The motor casing 3 is pivoted at 26 and the wheel 25 is pressed against wheel 24 by a compression spring 27 having an adjustable abutment screw 28. The pivot 26 may be located at the blower shaft bearing 7. The pivoted motor mounting may be used in the embodiment shown in Fig. 1, in which case the compression spring 27 is replaced by a tension spring, or compression springs are placed between the motor and the recess 22. Alternatively the positions of the pivot 26 and spring 27 may be transposed.

Abstract: 954,806. Gas turbine plant. BENDIX CORPORATION. Jan. 23, 1962 [March 2, 1961], No. 2472/62. Heading F1G. [Also in Division G3] In a gas turbine engine, which may be for jet propulsion purposes, as shown, with a single turbine 18 driving a compressor 16 or may have an additional turbine for driving a propeller or other load, a conduit 42 through which fuel is supplied by a pump 36 to burners 26 is provided with a throttle valve 48 which is actuated during stable operation by a servopiston 78 and during acceleration by a cam 54. The servopiston 78 is controlled by a ball valve 95 seating on an extension of the servopiston and actuated by a lever 90 which is positioned by cam followers 122, 88. The follower 122, which has a spring-loaded collapsible part 124, coacts with a cam 134 rotatable by a power control lever 140 and axially movable by a bellows 144 responsive to compressor intake pressure. The follower 88 coacts with a portion 62 of the cam 54 which, together with a cam 188, is moveable axially by a lever 212 and bellows 218 responsive to compressor intake temperature and rotatively by a servopiston 70 acting through a rack and pinion 68, 66 and controlled by a ball valve 162 actuated through a lever 164 by an enginedriven governor 176 which is loaded by a spring 206 acting on the lever 164 through a roller 202 positioned by a follower 190 coacting with the cam 188. The parts are shown in the positions they occupy during acceleration, when the cam 134 has been adjusted such that the servopiston 78 has engaged a stop 108 and the lever 72 has been moved away from engagement with a fulcrum 84 so that it is ineffective on the valve 48 and the latter is controlled by the cam 54 which is shaped to prevent compressor stalling. As the engine approaches the selected speed the cam 54 allows rightward movement of the follower 88 so that the servopiston 78 is caused to move to the left and engage the lever 72 with the fulcrum 84 whereafter the follower 50 is withdrawn from the cam 54 and the valve 48 is actuated by the servopiston 78 under the control of the factors acting on the lever 90. When rapid deceleration is selected the lever 90 engages a stop 226 which determines a minimum opening of the valve 48. A regulator 51 maintains a constant pressure difference across the valve 48. The pressure and temperature responsive bellows 144, 218 may be interchanged with each other. Specification 954,805 is referred to.
